我省中小型水库采用侧槽式溢洪道的为数不少,过去多数采用了所谓扎马林方法的不正确的水力计算方法,近年来这个问题已引起人们的注意。这里介绍南斯拉夫G.哈丁的一篇文章“侧槽式溢洪道”(译自第九届国际大坝会议报告第五卷)。文中主要内容是根据变量流微分方程式的大量积分计算资料(采用电子计算机)分析得出侧槽中水面线的简易计算方法,同时还根据试验研究资料和他人研究成果归纳出欲求侧槽水流有较好流态所必须满足的三项条件。其最后成果简单实用,对中小型水库侧槽式溢洪道的设计或研究有一定参考价值。指 Small and medium-sized reservoirs in our province use a large number of side-channel spillways. In the past most of them adopted the incorrect hydraulic calculation method called the Zamarin method. This problem has attracted people’s attention in recent years. Here is an article by Yugoslav G. Harding entitled “Slotted Spillway” (translated from volume V of the Ninth International Conference on Dams). The main content of this paper is a simple calculation method based on a large amount of integral calculation data of variable flow differential equation (using electronic computer), and also based on experimental research data and other research results, Good conditions must meet the three conditions. The final result is simple and practical, which has certain reference value for the design or research of side channel spillway of small and medium reservoirs. Means
